These small, yet energetic dogs might have less body mass than some other breeds—but don’t make the mistake of thinking that this minimizes their need for a quality, nutritional calorie base! Rat Terriers are intelligent, quick-on-their-feet, and friendly. They make excellent companions—and will live a much more active and fulfilling lifestyle if you feed them right!

This dog breed will generally grow to be between 13 and 16 inches tall (at the shoulder), and will end up weighing somewhere between 10 and 18 pounds. A Rat Terrier that’s less active in his or her lifestyle will generally consume somewhere around 380 calories per day, while an animal with a more moderately-active routine will eat more like 470 calories.

A highly active Rat Terrier, however, will need quite a bit more—somewhere closer to 740.

Just remember that different Terriers will have different individual weights and personalities—which will usually mean that their caloric requirements will be different as well. It’s a good idea to pay attention to your dogs when they eat, just to make sure that they seem to be getting enough to keep them going at their specified meal times.

Macronutrient Information for Rat Terriers

Like all dogs, Rat Terriers require a diverse and high-quality range of nutrients and foods to keep them happy, healthy, and going strong. Because they are a small-breed, they tend to be susceptible to a few different joint conditions—so a diet that’s full of Omega 3, Omega 6, Glucosamine, and Chondroitin will be immensely beneficial.

A grain-free dog food is best for this breed, as it helps to keep their digestive system cleaner. Meat based proteins are definitely the preferred source of energy for terriers.

A diet that’s rich in antioxidants, vitamins, and minerals will help to keep this dog’s immune system strong and capable—which will do a lot to keep him or her from getting sick and coming down with other diseases or conditions.

Common Health Problems

Rat Terriers tend to be pretty healthy little dogs, for the most part—though, like any other breed, they can get sick and deal with health problems from time to time. Dealing with such issues as they arise is usually a pretty common-sense ordeal, and may require a visit to the veterinarian.

Not all Rat Terriers will have all of these problems—but that doesn’t mean that it’s not good to be aware of what could go wrong. On that note, here are some of the most common health conditions that this breed tends to deal with.


Many dog breeds suffer from allergies—and Rat Terriers are one of them. Some symptoms of this problem may include itching, scratching, or irregular odors. Ear infections can also be caused by allergies—as can infections and irregular ‘bumps’ on the skin.

This article does a great job of explaining dog allergies and how to identify them—and is definitely recommended reading if you own a Rat Terrier.

Feeding your dog a high-quality kibble that’s grain free can do a lot to help alleviate allergy problems. It can also help to be selective when it comes to products like flea powders, shampoos, and bedding.

Patellar Luxation

This condition, also known as ‘trick knees’, occurs when the kneecap ‘slides out of place’. It happens in the rear legs, and can cause a lot of pain for your pet. Small dogs tend to be the most susceptible to it, and Rat Terriers are no exception.

Feeding your pet a diet that’s rich in glucosamine and formulated to be anti-inflammatory can do a lot to help prevent Patellar Luxation. Making sure that he or she gets enough quality exercise time to build muscle mass can also help.

This article does a great job of explaining the problem in greater detail—and I would recommend checking it out if you own any small-type dogs—including Rat Terriers.

Incorrect Bite

This condition is also known as ‘Malocclusion’, and refers to a condition in which the jaw is slightly deformed and misaligned. Rat Terriers can be prone to all three different types of the condition—and some severe cases might need to be corrected surgically.

The good news is that this problem sometimes solves itself as the puppy grows. The bad news is that surgery will probably be required if the problem interferes too much with the animal’s life and well-being.

This can be a complicated problem—so I would suggest taking a look at this article to get more information. It provides some pictures and does an awesome job of explaining the condition in-detail.

How to feed a Rat Terrier Puppy

Rat terrior dog food reviews

Rat Terrier puppies generally begin the weaning process between weeks 5 and 6 of age. Keep in mind that dogs need to have incisors and molars before they’ll be able to eat kibble—so it’s incredibly important to keep the puppy on its mother’s milk (if at all possible) before this process can be completed.

Rat Terriers do the best when they remain with their mother and birth-litter until they’re 7 to 8 weeks old. By this time, the weaning process will be complete, and the puppy will have been socialized enough to adjust to life with other animals and new people.

Most Rat Terrier pups will weigh around 3 pounds by the time they’re 8 to 9 weeks old—which means that they’ll need about 140 calories per day (usually separated into three separate meals) to stay fueled and energized.
